BENDING-ROLLS.

Specification of Letters Patent.

iatented Dec. 2e, aeoe.

Application filed September M, 1908. Serial No. 453,034.

citizen of the United States, residing at Middletown, Butler county, Ohio, have invented certain new and useful Improvements in Bending-Rolls, of which the following is a specification.

This invention, ertaining to improvements in bending roffs, will be readily understood from the following description taken in connection with the accompanying drawing in which Figure 1 is a front elevation of my improved'rolls, the buckle-bearing and its bushing appearing in vertical section: Fig. 2 an elevation of the tail end of the machine: Fig. 3 an elevation of the head end of the machine, the driving gearing and its support ing bracket being omitted: Fig. 4 a plan, part horizontal section, of the expansion gear-in and Fig. 5 a diagrammatic plan of the rol -adjusting mechanism.

In the drawing:-1, indicates the head housing: 2, the tail housing: 3, the bearings for the lower 1pinching roll, arranged to slide vertically in t e housings: 4, the lower pinching roll journaledin these hearings: 5, the

- fixed bearin in the head housing for the top pinching rol 6, the top pinching roll having its head journal mounted in this hearing: 7, the driving pulleys for the machine: 8, the gearing connecting the drivingpulleys with the two pinching rolls: 9, the buckle-bearin pivoted to the tail housing on a horizontal pivot and adapted to swing up and enga e and su port the tail ournal of the top inc 1- ing rol and 10, the tail journal of t e top pinching roll.

All of the parts thus far referred to are and may be constructed and arrangedfor operation as usual and subject to the usual modifications of such constructions.

Proceeding with the drawing :-11,- indicates a tapering bushing loose on the tail journal of the top inching roll and held against endwise disp acement by a collar on the outer end of the journal: 12, a tapering bore in the buckle-bearing, adapted to engage and fit the exterior of the bushing: 13, a

in projecting outwardly from the tapering ushing: and 14, a notch in the buckle-bearing ada ted to engage the pin 13 when the buckleearing is in active position.

' When the buckle-bearing is down, as shown in Fig. 1, then curved sheets may be readily withdrawn endwise of the rolls, and when the buckle-bearing is swun up into place the tapering bore of the buck e-hearing readily engages over the tapering portion of the bushing and the pin and notch arrange ment prevents the bushing from turning in the buckle-bearing The wear at the tail journal of the to pinching roll takes place entirely on that hearing and in the bore of the bushing and may, when occasion de-: mands, be compensated for by re lacing the tapering bushing, the bore of the bucklebearing being free from wear.

Proceedingwith the drawing:15, indicates diagonal slots in the two housings to receive thebearings of the bending roll: 16, the bearings for the bending roll, adjustable in these slots: 17 the bending roll: 18, non-rotary screws rojecting downwardly from the bearings of t is lower pinching roll: 19, bevelgears forming nuts on these screws, the gears beinghoused against vertical movementin the houslngs: 20, bearin s supported by and at the inner surface of t e housings in the com mon vertical plane of screws 18: 21, a shaft journaled in these bearings provided at its ends with bevel gears engaging the bevel gears 19: 22, a pinion fast on this shaft: 23, a

gear on the inner end of shaft 23, engaging withpinion 22. By turning shaft 23, through the medium of a crank, the lower pinching roll is raised and lowered.

Proceeding with the drawing:25,' indicates a shaft mounted in the housings near the bending roll: 26, a crank-receiving shaft geared to the shaft25, shafts 25 and 26 having --the same provision and operation in connection with the'bending roll that shafts 21 and 23 have to the lower pinching roll: 27, ex ansion gearing connecting the lower inc ling roll and the bending roll whereby t e three rolls are simultaneously driven: and 28, a latch-pin for-holding the buckle-bearing in elevated position.

I claim:

1. Bending rolls comprising, a pair of housings, a lower pinching-roll, a bending roll, adjustable bearings carried in the housings for the lower pinching roll and the bending roll, means for adjusting the bearings, a top pinching roll having its head-journal mounted in a bearing carried by the head hous- 7- ing of. the machine, a tapering bushing on the tail journal of the top pinching roll, a bucklebearing having its base mounted on the tailhousing of the machine on a pivot-axis at right angles to the axis of the rolls and having in its upper end a tapering bore adapted toengage t e tapering exterior of the bushing, and a latch to serve in retaining the buckle-bearing in upward position with its tapering bore in engagement with the bushing, combined substantially as set forth.

2. Bending rolls comprising, a pair of housings, a lower pinching roll, a boi'idin-g roll, ad-

jus'table bearings carried in the housings for the lower pinching roll and the bending roll,

means for adjusting the bearings, a top pinchmg roll having its headournal mounted in a bearing carried by the head housing of the machine, a tapering bushing onthe tail journal of the top pinching roll, a buckle-bearing having its base mounted on the tail-housing of the machine on a ivotaxis at right angles to the axis of the rol s and having in its upper end a tapering bore adapted to engage the tapering exterior of the bushing, a cooperating pin and notch on the buckle-bearing and bushing to positively prevent rotation of the bushing, and a latch to serve in Ieta'inin the buckle-bearing in upward position Wit its tapering bore in engagement with the bushing, combined substantially as set forth.
